Outlook PST file offline synchronization in Win7

    Question

  • Hey Everyone, 

    Been doing some work with a user that had just moved over to Windows 7 who was complaining about how Outlook was complaining about not finding PST files while offline. 

     

    Does anyone know if PST files are supported for offline availability? I've tested with my test machine and it seems like the Synchronization center will make copies of them when Outlook is closed.  I know in XP there was a KB article (http://support.microsoft.com/kb/252509) that said by default it was skipped in 2K/XP. 

    Let me know if this is a good idea or a bad one or if I run the risk of corrupting one of the PST files. 

     

    Thanks

  • Hi there,

    Offline folders will break .pst files. An option to tackle this issue is to exclude pst files from synchronising with offline files. but it will be harder for users to understand what is, and what isnt automatically synched with the homedir on the network.

    This is the reason why we choose not to implement offline files. we tried it on Windows 7 with Outlook 2010.

    thats my experience iwth it, if someone has cunning way to make it work. please share!

  • Hi Arthur,

     

    Thanks for the response, however the KB article mentioned didn't have much to do with the issue that I'm having. The user has a Win7 Laptop and is doing offline synchronization of the PST files.

     

    In the past I know it wasn't possible to do this due to the type of the file, but since Windows 7 uses a different method of synchronization. Is it still a good idea to do so or would it be easier to just place a local copy on the user's machine?

     

    Thanks

  • As far as I can tell (not having done extensive testing) - the basic answer to your question is "Yes, Win7 Offline file synchronization will indeed synch/cache an Outlook PST file" - something WinXP could not do.

    That doesn't mean it is a good idea, or even reliable.  Please take a look at the article below:

    http://technet.microsoft.com/en-us/library/cc749449(v=ws.10).aspx

    As I read this, Win7 will ATTEMPT to synch a .PST file.  But if Outlook is open and connected, then that synch will fail.  You would have to close Outlook (thus closing the PST file) - then manually execute a synch of the PST file.

    Notice the statement in the article:

    ImportantImportant
    Because Offline Files will not synchronize changes for files that have open handles, files that are usually open for long periods of time and that are prone to change, will not automatically be synchronized. An example of this type of file is an Outlook PST file. To synchronize this type of file, you must close the application that uses the file and start a manual synchronization process.
